Abstract
A nose respirator device with a holder connected to a base. The holder has a top which is configured to sit on a nasal bridge and is joined on each side with an arm which extends downward and each arm joins the base which is configured to sit across a subnasale underneath nose tip. The base contains two separate open cavities, each open cavity has an upper opening shaped like a cone suitable for insertion into a nostril. Each open cavity of the two separate open cavities can be further divided by a separator into two channels. Valves installed along inside wall of each channel control air flow as the valves are configured to open only in one direction when being pushed by air current. Filters can be fitted into each cavity or each channel within each cavity for air cleaning.
